Three new papers find sugars, “gum,” and lots of stardust in the samples brought back from the asteroid Bennu

Bennu
The asteroid Bennu

Three new papers published this week have found that the samples brought back by OSIRIS-REx from the asteroid Bennu contained some unexpected or unusual materials, including sugars that are important for biology, a gumlike material never seen before, and a much higher amount of stardust than expected.

The papers can be read here, here, and here.

As the press release notes, describing the sugar discovery:

The five-carbon sugar ribose and, for the first time in an extraterrestrial sample, six-carbon glucose were found. Although these sugars are not evidence of life, their detection, along with previous detections of amino acids, nucleobases, and carboxylic acids in Bennu samples, show building blocks of biological molecules were widespread throughout the solar system.

The stardust results found six-times the abundance previously found in other samples.

As for the “gum”, this was possibly the strangest discovery of all, coming from the solar system’s earliest time period.

All eight ports on ISS occupied for the first time; Longest manned mission about to start?

ISS as presently configured
ISS as presently configured. Click for original.

For the first time in its more than quarter century history, all eight docking ports on ISS are occupied, as shown in the graphic to the right.

For the first time in International Space Station history, all eight docking ports aboard the orbital outpost are occupied following the reinstallation of Northrop Grumman’s Cygnus XL cargo spacecraft to the Earth-facing port of the station’s Unity module. The eight spacecraft attached to the complex are: two SpaceX Dragons, Cygnus XL, JAXA’s (Japan Aerospace Exploration Agency) HTV-X1, two Roscosmos Soyuz crew spacecraft, and two Progress cargo ships.

This milestone follows the reattachment of the Cygnus XL spacecraft, supporting the Northrop Grumman-23 commercial resupply services mission for NASA, which was removed last week by the robotics officer at the agency’s Mission Control Center in Houston using the space station’s Canadarm2 robotic arm. The Cygnus XL movement was coordinated between NASA, Northrop Grumman, and Roscosmos to provide appropriate clearance for the arriving crewed Soyuz MS-28 spacecraft on Nov. 27.

Cygnus will remain attached to the orbiting laboratory until no earlier than March 2026, when it is scheduled to safely depart and dispose of up to 11,000 pounds of trash and unneeded cargo when it harmlessly burns up in Earth’s atmosphere.

This situation will not last of course, and in fact it may never happen again before the station is retired around 2030. First, Cygnus will leave in March. Second, one Russian Soyuz capsule will leave shortly, as the presence of two simply indicates a crew rotation is underway.

Third, it is presently unclear when the Russians will be able to launch further Soyuz or Progress capsules. » Read more

China reveals its plans for the damaged Shenzhou-20 capsule docked to Tiangong-3

with two Shenzou capsules docked at either end.

Having successfully docked Shenzhou-22 as a lifeboat to its Tiangong-3 space station last week, China’s state-run press yesterday outlined its plans for the damaged Shenzhou-20 capsule that is still docked to the station but cannot be used by its crew because of cracks in one viewport.

First, China’s space operations have decided to attempt a return of the capsule back to Earth, unmanned, so the damage can be inspected in greater detail. Before that happens however the astronauts on board the station will do their own inspection, including the possibility of adding a patch.

During a subsequent spacewalk, the Shenzhou-21 crew, who are now undertaking a six-month orbital stay, may be tasked with inspecting the cracked viewport. They may also perform protective work on it using specialized devices delivered by the Shenzhou-22 launch — a procedure still being validated in ground tests, said Ji in a recent CCTV interview.

A day prior to their planned return on Nov. 5, the Shenzhou-20 crew spotted an anomaly on the viewport’s edge — a triangular, paint-like mark. They photographed it from multiple angles and under different lights, while the station’s robotic arm cameras were employed to take supplemental external pictures.

The flaw was later identified as “penetrating cracks,” said Jia Shijin, chief designer of the crewed spaceship system from China Academy of Space Technology. “The space debris responsible is preliminarily judged to be less than a millimeter in size, but struck with extremely high speed.”

This description of the damage is the most detailed China as yet revealed. These details certainly fit the description of an impact from an outside source, though considering China’s general lack of transparency some skepticism should still be retained. For example, we still do not know if these “penetrating cracks” mean the capsule is no longer holding its atmosphere, or if the crew has closed the capsule’s hatch to keep the air loss to a minimum.

Either way, it appears China’s engineers are concerned that this damage could cause a major break-up of the capsule during re-entry, and are thus considering options for covering it during that return.

German rocket startup Isar gets launch contract from ESA

The German rocket startup Isar Aerospace yesterday announced it has won a launch contract from the European Space Agency (ESA) to place a satellite carrying a number of experimental payloads into orbit before the end of 2026.

Satellite launch service company Isar Aerospace has signed a contract with the European Space Agency (ESA) to launch the ΣYNDEO-3 mission under the European Union’s In-Orbit Demonstration and In-Orbit Validation Programme (IOD/IOV). The launch will be carried out from Isar Aerospace’s dedicated launch complex at Andøya Space in Norway from Q4 2026.

…Redwire is the prime contractor for the ΣYNDEO-3 mission and will be delivering its Hammerhead spacecraft for a launch onboard Isar Aerospace’s launch vehicle Spectrum to a low Earth orbit (LEO). The spacecraft was built and integrated at Redwire’s state-of-the-art satellite processing facility in Belgium. The spacecraft aggregates 10 innovative payloads from six countries and institutions: Spain, France, Germany, Italy, Luxembourg and the EC.

Isar has yet to reach orbit with its Spectrum rocket. The first launch failed in March only seconds after launch. A second attempt is presently scheduled for sometime prior to December 21, 2025, lifting off from Andoya.

This is the second new launch contract Isar has announced in the past two weeks, and the third since September. At the moment it appears it is gaining momentum pending that first launch later this month, especially because a successful December launch would make it the first European rocket startup to successfully reach orbit.

Senate Commerce committee to move up its vote on Isaacman’s nomination as NASA administrator

Jared Isaacman
Billionaire Jared Isaacman

Today Senator Ted Cruz (R-Texas) announced that the Commerce committee he heads will vote on the re-nomination of Jared Isaacman for NASA administration on December 8, 2025, only five days after tomorrow’s renomination hearing.

It appears Cruz and his committee is pushing to get Isaacman approved as quickly as possible. At least one Republican senator, John Cornyn (R-Texas) has met with Isaacman again and gotten his commitment to move the space shuttle Discovery to Texas, as mandated by the budget bill passed several months ago. That commitment was likely a quid pro quo by Cornyn to get his vote for Isaacman.

Once Isaacman is approved by Cruz’s committee, the Senate could vote at any time. Whether it will do so before the end of the year remains unknown, as it would likely require a special session as the Senate is expected to be in recess until after the new year.

If it does not, it will likely give Isaacman very little time to review the next Artemis mission, tentatively schedule for launch as early as February 2026, carrying four astronauts around the Moon on a Orion capsule with a questionable heat shield and an untested environmental system.

SpaceX gets Air Force approval to launch and land Starship/Superheavy at Cape Canaveral

Cape Canaveral

The Air Force announced late yesterday [pdf] that it will now allow SpaceX to launch its Starship/Superheavy rocket at Space Launch Complex 37 (SLC-37) at Cape Canaveral in Florida (as shown on the map to the right) as many as 76 times per year, with twice that number of landings.

The DAF [Department of Air Force] decision authorizes SpaceX to use SLC-37 at CCSFS [Cape Canaveral Space Force Station] to support Starship-Super Heavy launch and landing operations, including the redevelopment of SLC-37 and the other infrastructure improvements required and analyzed in the FEIS [Final Environmental Impact Statement]. Under this ROD [record of decision], upon execution of the real property agreement and associated documentation, and as analyzed in the FEIS while adhering to the mitigation measures specified in Appendix A to this ROD, SpaceX is authorized to: (1) undertake construction activities necessary to re-develop SLC-37 and associated infrastructure for Starship Super Heavy operations; (2) conduct prelaunch operations, including the transportation of launch vehicle components and static fire tests; and (3) conduct up to 76 launches and 152 landings annually once a supplemental analysis of airspace impacts by the Federal Aviation Administration (FAA) is completed. [emphasi mine]

The deal also requires SpaceX to do some road upgrades in order to transport the rocket from its Gigabay to the launch tower. The company immediately announced on X yesterday that it has already begun construction, and expects to have three pads in Florida before all is done.

The final environmental impact statement [pdf] was released on November 20, 2025, and concluded in more than 200 pages that there will be no significant impact from these launch operations, something that should be self-evident after more than three-quarters of century of rocketry at the Cape. The existence of the spaceport acts to protect wildlife, because it limits development across a wide area.

The report suggested that some turtle species and one mouse specie might “affected adversely”, but it it also appears that risk was considered minor and not enough to block development. To deal with this however the impact statement requires SpaceX to do a number of mitigation actions, similar to what it is required to do at Boca Chica.

One fact must be recognized, based on the red tape and delays experienced by SpaceX during the Biden administration. Had Kamala Harris and the cadre that ran the White House under Biden had been in office now, this approval would almost certainly have not happened, or if it did, it would have likely been delayed for a considerable amount of time, into next year at the earliest. It is certain that Trump is clearing the path to prevent red tape and the administrative state from slowing things down unnecessarily.

This announcement also strengthens the likelihood that SpaceX will do at least one launch of Starship/Superheavy from Florida in 2026. And if not then, by 2027 for sure.

Two launches today, by Arianespace and SpaceX

Today there were two launches worldwide, one from South America and the second from the U.S.

First, Arianespace launched a South Korea imaging satellite from French Guiana, using the Vega-C rocket built and owned by the Italian rocket company Avio. Based on the July 2024 agreement, this is the next-to-last Vega-C flight that Arianespace will manage. After the next flight, Avio will take over management of its own rocket, cutting out this government middle man, though that agreement also allowed customers who had previously signed with Arianespace for later flights to stay with it as the managing organization.

Either way, Arianespace’s responsibilities will soon be limited solely to the Ariane-6 rocket, which itself has a limited future, being expendable and too expensive to compete in the present launch market.

Next SpaceX launched another 27 Starlink satellites into orbit, its Falcon 9 lifting off from Vandenberg Space Force Base in California. The first stage completed its 20th flight, landing on a drone ship in the Pacific.

As the Vega-C launch was only the sixth for Europe in 2025, it remains off the leader board for the 2025 launch race:

157 SpaceX (a new record)
74 China
15 Rocket Lab
15 Russia

SpaceX now leads the rest of the world in successful launches, 157 to 126.

Buffalo Bill: The greatest true boy adventure story that’s never been told

The Lives and Legends of Buffalo Bill

In American popular culture, Buffalo Bill is an icon whose history we all think we know, a western showman who in the latter decades of the 19th century traveled the world with his Wild West show, enchanting heads of states as well as ordinary people with the romantic fantasy of the American west, made up of wagon trains, gunfighters, Indian attacks, and last-minute cavalry rescues.

His name inspired the name of a professional football team. His Wild West show inspired at least one musical and numerous Hollywood movies and television shows.

Yet do we really know who the man was?

I discovered recently that we do not. Our culture knows nothing about the man, whose real name was William Cody. Worse, its cartoon vision of him denigrates his unique American nature. He was not only the greatest scout the U.S. Army ever saw, his knowledge of American Indian made it possible for him to not only help make peace with those Indians who wanted it, it also helped the U.S. put down those Indians willing only to wage terrorist war. And when he shifted into the entertainment world, his show provided employment for both his many cowboy friends as well as for many of those same Indians, both friends and former enemies.

And most astonishing of all, I discovered that Buffalo Bill’s childhood was one of the most amazing boy adventure tales, far more exciting than any kid’s movie made in the last hundred years. That Hollywood has never made a movie of his youth now baffles me. It is the stuff that Hollywood craves, but more significantly, it appears it actually happened!

I discovered these facts in reading Don Russell’s wonderful biography of Bill Cody, The Lives and Legends of Buffalo Bill, published by the University of Oklahoma in 1979. Russell’s focus was to dig into the original source material in order to separate the fact from the fiction, since much of Cody’s life had been exaggerated by himself and others during his showman days, and then overblown and warped by Hollywood’s later interpretations.

In this Russell succeeds brilliantly. He describes what we know in vivid language, but also outlines what we don’t know or can’t trust about each story. In the end he describes a unique man with unique talents who always tried to do the right thing, even in difficult circumstances. In every sense Cody’s life was the epitome of an American western pioneer cowboy, pushing the unknown with courage and pluck.

But to me the most amazing part of Russell’s biography was its first few chapters, when Russell describes Cody’s childhood. The boy’s father, Isaac Cody, was a pioneer in his own right, taking his family farther and farther west until they ended up in Kansas and involved in the violent politics there preceding the Civil War. When Isaac died in 1857, he left behind a widow and three young children, who then had to find a way to survive in that difficult pioneer world.

And so, at the age of eleven Billy Cody went out to find work. And the work the boy found was truly astonishing, when compared to what we expect from kids his age today.

A detailed look at Europe’s $1 billion commitment to its nascent commercial rocket industry

The European Space Agency

Link here. In announcing last week the European Space Agency’s (ESA) budget for the next three years, along with its general overall goals, the European council (dubbed CM-25) also apparently committed about $1.45 billion to its “European Launcher Challenge”, a program created in 2023 and designed to encourage the development of new European rockets, owned and operated by independent competing startups.

The article at the link provides a good overall summary of major increase in funding for this program, including which ESA countries are contributing the most and why. The key quote however is this:

In July 2025, ESA shortlisted Isar Aerospace, Rocket Factory Augsburg, PLD Space, MaiaSpace, and Orbex to proceed to the initiative’s next phase. It then began discussions with the host country of each company to assess its willingness to contribute to that company’s participation in the European Launcher Challenge.

During his post-CM25 address, ESA Director General Josef Aschbacher revealed that Member States had committed double the anticipated amount for the European Launcher Challenge, with the final figure exceeding €900 million. While the funding model’s structure suggests that only the UK, Spain, France, and Germany contributed, post-CM25 disclosures have indicated that a few additional countries also committed funds to the programme.

Germany appears to be the biggest contributor, supplying more than a third of the total fund ($422 million). This isn’t surprising, since Germany also has the most rocket startups, three, two of which are on that shortlist (Rocket Factory and Isar). Spain is next with a contribution of $196 million, aimed helping the rocket startup PLD. The UK is next, also contributing $196 million, likely to be used to support its Orbex startup that wants to launch from its Saxavord spaceport in the Shetland Islands.

A variety of other ESA nations, the Czech Republic, the Netherlands, and Norway, have also outlined their contributions, for a variety of space-related startups unrelated to rockets.

France also appears to have donated a significant amount, but has not made that number public. Its MaiaSpace startup is one on that shortlist above, but France also has one or two other rocket startups that might eventually qualify for aid.

The bottom line is that ESA here is committing funding to aid the development of rockets and space infrastructure that it won’t own or control, a major shift from its past policy of owning and controlling everything through its Arianespace pseudo-commercial company, what I call the Soviet- or government-run model. Instead, these ESA nations are going to help fund a range of competing private rockets, which will own the rockets and operate them for profit. ESA will simply become one of their customers, following the capitalism model that the U.S. switched to in the previous decade.

This increased commitment to capitalism in the ESA suggests that we should see some real progress by these startups in the next three years.

If you think the launch records being set this year are breath-taking, you ain’t seen nothin’ yet.

After being linked for almost six months, China’s Shijian 21 and Shijian 25 separate

After rendezvousing and doing repeated docking tests in June and July and then remaining linked since then, China’s Shijian 21 and Shijian 25 test satellites have now separated.

Optical ground observations Nov. 29 made by S2a systems, a Swiss company which develops and operates customized systems for optical space surveillance worldwide, reveal that the two satellites have now separated in geosynchronous orbit, close to the geostationary belt (GEO) at 35,786 km above Earth’s equator. The orbits of the pair are inclined by 4.6 degrees with respect to GEO.

The article at the link speculates that the spacecraft were doing refueling tests while docked, but while a good guess this has not been confirmed anywhere. China has said nothing.

Shijian-21 was launched in 2021, and was used to grab a defunct Chinese geosynchronous satellite and tug it to a graveyard orbit. Shijian-25 was launched in January 2025, apparently intended to test robotic servicing of satellites. These maneuvers with Shijian-21 appear to be part of those tests. Whether those tests included refueling is uncertain, though possible. If Shijian-21 proceeds to do additional satellite tug maneuvers then it will strongly suggest this refueling occurred and was successful.
